[0028] Specific working principle:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the easily replaceable dust filter element is used, the upper mounting plate 2 and the lower mounting plate 5 are fixedly installed with the filtering device. When it is necessary to move the limit rod 7, the block 13 on the outer side of the limit rod 7 is pressed inward. After the metal spring 12 is compressed, the block 13 enters the interior of the filter element upper plate 3, and the limit rod 7 can be rotated on the inner side of the upper slide groove 8 and the lower slide groove 6. The limit rod 7 drives the joint 10 to slide on the inner side of the limit groove 9. After the limit rod 7 is turned away, there is no limited cover on one side of the filter element body 1, and the filter element body 1 can be taken out for cleaning or replacement. When installing, put the filter element body 1 into the upper mounting plate 2 and the lower mounting plate The plates 5 are arranged between the filter element upper plate 3 at the upper end of the filter element body 1 and the lower surface of the upper mounting plate 2, and the lower end of the filter element lower plate 4 is fitted with the upper surface of the lower mounting plate 5. The sealing ring 14 plays a role of sealing reinforcement. After the filter element body 1 is properly placed, the block 13 is pressed inward, and the limiting rod 7 is rotated to the corresponding position again and then the block 13 is used for limiting. The limiting rod 7 can be limited at the outer ends of the filter element upper plate 3 and the filter element lower plate 4 to realize the disassembly and replacement of the filter element body 1. The above completes a series of operations of the dust removal filter element which is easy to replace.
